JACOB HESSLER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE W. W. KIMBALL COMPANY, OF SAME PLACE.

COUPLER FOR SPECIFICATION forming part of Letters Patent No. 357,598, dated February 15, 1887.

Application filed June 13, 1885.

To all whom, it n tay concern.-

Be it known that I, J AOOB HESSLER, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois,

have invented a new and useful Improvement in Couplers forReed-Organs, of which the following is a specification.

In cabinet-organs the treble octave-couplers act upwardly-that is to say, they couple with [O the note struck the corresponding note in the octave next above. It results from this law of their organization that those notes whose corresponding octave-note would be beyond the limit of the board are necessarily left un- I 5 coupled, in the sense that when they themselves are struck no octave-note sounds with them, though of course they are sounded by the couplers with the playing of the octave next below. The notes of which this is true embrace all the upper octave except the lowest note thereof, and as they are unsupported when struck a marked diminution of volume is no ticeable when the player passes to them from the coupled notes below. This has been sup- 2 5 posed to be an evil without remedy, owing to the fact that there are no notes above the board to which the uncoupled notes can be connected.

My invention is designed to overcome this objection; and it consists in the combination,

with the upper uncoupled notes above mentioned, of octave-couplers acting reversely and coupling said notes with their corresponding notesin the octave below, substantially as hereinafter specified.

In the accompanying drawings, forming a part of my description of the invention, Figure 1 is a plan view of the couplers, showing my reversely-acting couplers in position, and also the ordinary upwardly-acting couplers. Fig. 0 2 is a transverse sectional view through the couplers, showing the latter in the position occupied when they are not employed. Fig. 3 is a view similar to Fig. 2, showing the couplers in action. Fig. 4 is a plan of the eccen- 5 tries for lifting the coupler-boards. Fig. 5 is an end view showing the connections between the eccentrics and the organstop for bringing the couplers into action.

In the drawings, A A represent the keys Renewed January 8, 1887. Serial No. 223,819.

forming the key-board of the instrument, each having the usual tracker-pin a. Those of the keys which couple upward carry also pins B, for operating the couplers, whilethe uncoupled keys (meaning those forming the upper octave ofthe instrument, except the lowest note of that octave) carry pins b, for operating the reversely-acting couplers.

O is the board carrying the upwardly-acting couplers c. Said board is hinged in the usual manner, and is raised at the front edge by the bend d in the pivoted wire D when it is desired to bring the couplers into action. These parts do not differ from those heretofore used. In the rear of board 0, I place another similar board, E, also hinged and carrying another series of couplers, e, and this board is raised at the rear end for thelike purpose by a bend, f, in the pivoted wire F, similar to the bend d and wire D. These couplers e are operated bythepinsb,attachedtothehithertouncoupled upper keys of the instrument, and they extend to and connect with the tracker-pins of the correspondingly-lettered keys in the octave next below, as clearly illustrated in Fig. 1, the keys of the upper part of the key-board being shown in dotted lines. When thus coupled, these upper notes are as powerful as their neighbors in the octave below, and hence the difference in volume referred to is obviated.

In order that the stop G, when pulled out, may simultaneously bring both sets of couplers into position for action I connect it to both of the bent wires D and F. This may be done by attaching the stop to one end of a lever, fast upon the wire F, and connecting the other end of said lever by the linlcpieceH to a crank, it, on the end of wire D. Other connecting mechanism may be used, however.

It will be noticed that both the ordinary couplers and the reverse couplers are connected to the same notes, so that the notes are sounded by one set, while they themselves operate the other set to sound the octaves. This feature may be used in other parts of the instrument than that here illustrated.

I claim- 1. In combination with the keys of the uppermost octave of a cabinet-organ, the reverselyacting octave-couplers coupling said keys with the corresponding keys in the octave below, substantially as specified.

2. In a cabinet-organ, the combination of the reversely-acting couplers e, the board E, the bent wire F f, and the stop G with the keys operating said couplers, substantially as specified.

3. In a cabinet-organ, the combination of a series of upwardly-acting octave-couplers and a series of downwardly-acting octave-couplers, both connected, as described, to the same keys, substantially as specified.

4. In a cabinet-organ, the combination of a series of upwardly-acting octave-couplers, both I 5 connected to the samekeys, and a series of downwardly-acting octave-couplers, and a stop, G, connected to both series, substantially as set forth.
